Rattling is my favorite for drawing buck to my stand. Early in the season I will lightly touch the tines together for about 30 to 45 seconds then stop. I’ll wait about an hour or so that do another set. During the rut, bang the sh** out of them in longer sequences and more often. But during the rut, be ready. I have had results from a curious walk directly at my stand to an outright run across the field with ears back right at my stand to kick some butt. Experiment, it works with a little practice.
